Selecting data into a Postgres array

I have the following data:

name          id             url

John          1              someurl.com
Matt          2              cool.com
Sam           3              stackoverflow.com

How can I write an SQL statement in Postgres to select this data into a multi-dimensional array, i.e.:

{{John, 1, someurl.com}, {Matt, 2, cool.com}, {Sam, 3, stackoverflow.com}}

I've seen this kind of array usage before in Postgres but have no idea how to select data from a table into this array format.

Assuming here that all the columns are of type text.
